I purchased this item new two years ago and have been using it until recently. I dropped the grip once during use, and there are scratches as shown in the photos (Photo 2). There are no problems with its use. I don't mind it, but please refrain from purchasing if you are concerned. Since it is something used on the floor, I think it will get scratched easily (Photo 3). This is a used item. If you have excessive expectations, I recommend purchasing a new one. When listing, I replaced the batteries with new ones. Also, I have re-registered it in the app and confirmed that it works without any problems (Photo 11). This is a listing for the main unit only, and the instruction manual and outer box are not included, but the instruction manual can be downloaded from the official website or viewed on your smartphone.
